not much use against real snipers, as opposed to someone taking a pot shot.
Someone sniping from 600m would be on his toes ages before the sound hit the target. And thats assuming the sound ever did reach the target.
The British army in NI had a device that picked up the crack of the sound barrier being broken as the bullet whizzed by, but that was much cruder and only gives a rough approximation. Much different than listening for the sound of the rifle itself.
In WW1 they'd pop a wax head over the parapet, and when a German sniper put a bullet through it they could tell by the track where he was.
Then they'd return fire using special rounds which had been turned back to front, so when the flat end hit the steel plate shielding the sniper, a shock wave would blast off or "spall" a fragment the other side and generally kill him. Worked a treat apparently.
I've also heard that DARPA are developing, or have done, bullets containing tiny microchips and small tail fins that steer them during flight, within ballistic limits presumably, to lock onto and hit a target several miles away.
I wonder ... when at a certain university, doing Engineering (snore), for my final year assignment I developed an acoustic-based system that pinpointed imperfections in metal, whilst it was being drilled/milled/turned/etc.
The bloody MOD have nabbed my idea! I want my compo!
It could, of course, make them even more of a target as the bad guys seek to acquire one of the little gizmos for themselves (now that we've told them all about it).
